TANK-HEATER.

1,256,560. Specification of Application filed August 26 To all whom tmay concern:

yBe it known that l, SAMUEL Hirn, a citizen of the United States,residing at Atwood, in the county of Kosciusko, State of Indiana., haveinvented a new and useful Tank-Heater;- and l do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others' skilled in the art to which it appertains tomake and use the same.

The present invention relates to certain new and useful improvements intank heaters,land has for its object to provide a device of thischaracter which embodies` novel features of construction whereby thewater in a drinking trough or fountain can be readily kept from freezingyin cold weather.

Further objects of the invention are to provide a device of thischaracter which is comparatively simple and inexpensive in itsconstruction, which will warm the water within the trough in aneffective manner so that it will not freeze in cold weather, whichadmits of the heater being detached from the trough when not in use, andwhich can be ouickly assembled or taken apart.

wWith these and other objects in view, the invention consists in certainnovelcombinations and arrangements ofthe parts as will more fully appearas the description proceeds, the novel features thereof being point-e edout in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is afront elevation of a tank heater constructed in accordance with theinvention, portions of the smoke pipe being broken away.

Fig. Q is a vertical longitudinal sectional view through the same.

Fig. 3 is a top plan view with the upper end of the smoke pipe removed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral 1 designates a drinking troughwhich may be conveniently formed of sheet metal and which is open at thetop, said trough being supported in an elevated position in any suitablemanner, as by means of the standards 2. A flue 3 extends upwardly froman opening in the bottom of the trough 1, the

lower e-nd of flue having a water tight connection with the edges of theopening, while the upper end of the flue extends above the top of thetrough and is provided with the diametrically opposed bayonet slots 1.The water 5 in the trough 1 surrounds the line 3, the said flue beingpreferably located at substantially the center of the trough.

Extending transversely across the bottom of the trough 1 is a pair ofguide members 6 which have a parallel relation to each other, and may beconveniently formed from Z bars. Ther exterior of the trough 1, andthebottom thereof, with the exception of theV area between the guidemembers 6 is covered with layer 7 of insulating material, such asasbestos, thereby preventing radia tion of the heat from the sides ofthe trough.

A lire box 8 is adapted to be applied to the bottom of the trough, thetop of the fire box beingprovided with lateral flanges 9 which engagethe guide members 6, and being also provided with an opening 10 whichregisters with the lower end of the flue 3 when the lire box is inposition. The front of the fire box is provided with the door 11 forclosing the opening through which fuel is placedinto the fire box. Belowthe door 11 is a second door 12 which has a damper controlled draftopening 13 therein, said door normally closing the opening through whichthe ashes are removed. This fire box can be readily inserted in positionor removed therefrom, and may be constructed of sheet metal, beingadapted to burn wood or coal as occasion reoluires.

After the lire box has been mounted in position a smoke pipe 14 isinserted in the iiue 3, the lower end of the smoke pipe being slightlycontracted at 11a, so as to tightly engage the edges of the opening` 10in the top of the fire box. This smoke pipe is provided with theconventional form of damper 15, the damper spindle 16 projecting uponopposite sides of the smoke pipe and engaging the bayonet slots 4 in thetop f the flue 3 when the smoke pipe is in position. This smoke pipeextends a suitable distance above the trough 1, the upper end thereofbeing provided with a cap 17 which has a screen 18 fitted therein toprevent the escape of live sparks. Vhen the parts are properly assembledand a tire started in the box 8 the water within the trough 1 is heatedso that it will not freeze in cold weather. In mild weather when it isnot necessary to use the heater, the fire box and smoke pipe can bereadily removed. All of the parts are readily accessible for the purposeof making repairs, and the entire device can be constructed of sheetmetal, so that the cost thereof will not be excessive.

In order to insure the heating of the Water at the ends of the tankwhich is some distance from the fire box and flue, a series of heatingpipes are extended along the bottom of the tank from the lire box towardboth ends of the tank. In the present instance .elbows 20 are shown asthreaded in openings in the bottom of the tank which register withopenings 2l in the top of the fire box, the said elbows being arrangedupon oppo` site sides of the Hue 3. A manifoldl 2z is Varranged neareach end of the tank and is connected to the elbows 20 by small pipes ortubes 23. The heated gases from the furnace may thus pass upwardlythrough the openings 2l in the top of the fire box and circulate throughthe pipes 23 and manifolds 22 so as to heat the water in the ends oftank which would not, especially in extremely cold weather, be heated bythe ire box and flue 3 alone.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is
